Gas Chromatographic Analysis of Anthracene Oil

Abstract

Fused-silica capillary chromatography combined with mass spectrometry has been used for the qualitative and quantitative analysis of anthracene oil. The analytical system consists of Hewlett-Packard 5880 gas chromatograph with a SP-2100 or OV-1 capillary column (50 m X 0.2 mm) and a Hewlett-Packard 5992 mass spectrometer. Standard mixtures were obtained by alkylation or hydrogenation of pure polynuclear aromatics. The gas chromatogram by an FID-detector is given in Fig.1 and identification and quantitation of the peaks are listed in Table 2. More than 140 components were separated and identified. Nitrogen-containing compounds were analysed by using an NP-detector. The results are shown in Fig.2 and Table 3. The acidic compounds in anthracene oil were also analysed to give the results shown in Fig.3 and Table 4.
